Minimum requirements for running UM7.3

Description

Hi,

I would like to run the UM7.3 (atmosphere) from a minimal configuration. Could you tell me what are the minimum prognostic variables that I need to start from?

If it is possible to switch off some part of the code, could you let me know which ones (e.g. land hydrology?). I would be happy with a downgraded version of the UM to begin with…

Please let me know if my request is unclear and if you need any further clarification.
Many thanks,
Aurélien

Hi Aurelien,

You need the following,

  • skin temperature,
  • surface pressure,
  • land-sea mask,
  • geopotential,
  • temperature,
  • specific humidity,
  • U and V wind velocities.

The first four are surface level fields.

Regards,

Willie

Thank you Willie!
I'm planning to switch off different sections of the model as well (e.g. hydrology, river routing, etc.). I'll tell you how it goes.
Many thanks,
Aurélien
